The speaker cannot connect to a wireless network. This problem may have several causes:
Wrong wireless network information and/or a failure in the connection between the speaker and the home network. Ensure that Wireless Network Name and Wireless Network Password are correct. If you use special characters such as #,&, % or any national characters in either your Speaker Name, Wireless Network Name or Wireless Network Password, please replace these characters with alphanumeric characters only.
The speaker can't locate the wireless network. If you have several WiFi networks in your home, try to turn off the ones not used by the speaker.
Try a factory reset and be sure that your wireless network is running with 2.4GHz only!
